Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine wheather the monitored vitamin D (vit D) therapy is safer and more effective than standard therapy in pretrem infants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Vitamin D (vit D) deficiency is a risk factor of osteopenia of prematurity, which leads to rickets or decreased bone mass mineral density. Recently multiple studies have been published on vit D adjust biological functions. Dosage, safety and effectiveness of vitD supplementation in preterm infants still remains a controversial topic. We hypothesize that monitored supplementation of vit D is more effective and safer than standard therapy 500IU in preterm infants. The study will be carried out in 138 preterm infants, born at 24-32 week of gestational age (GA) at the Princess Anne's Hospital in Warsaw, Poland. We will determine if monitored supplementation of vit D decreases the incidence of vit D deficiency and/or overdosing at 40 week (GA). For secondary objective we shall assess if monitored therapy reduces the incidence of vit D deficiency and/or overdosing at 35, 52 week (GA), prevalence of osteopenia, low bone mass, nephrocalcinosis and nephrolithiasis.
